Improvements in Apparatus for Shoveling,

Lifting, Carrying, and Dumping Material, of'which the following is a specification.

My invention relates to an apparatus for shoveling, lifting, carrying, and dumping material, and more particularly to an apparatus of this type for use in boats designed for carrying bulk freight, such as nature.

In unloading bulk freight such as iron ore, coal, and the like, the machinery for removing the bulk of the "freight or cargo is situated outside of the boat and by means of suitable parts or adjuncts, the material is lifted through the various hatchways of the boat, and in the'process of unloading, either the boat or. the unloading apparatusmust be .moved, so that after the material is drawn up from a point beneath one hatchway, the boat and unloading apparatus are moved relatively so that the material can be drawn up through" another hatchway. After the material within reach of the unloading implement, after working through all hatchways, has been removed from the regions beneath the various hatchways or within reach of the unloading implement, manual labor is resorted to for the purpose of shoveling or otherwise depositing the remaining inaccessible portion of thecargo into the regions where itcan be unloaded by the This, however, is very laborious and expensive and exceedingly slow work and 'detains the boat at the wharf or'dock, whereas it could be delivering a return car 0 and increasing its annual capacity considerably, if unloaded in less time.

The primary object of. my invention is to dispense with the manual labor required in shifting the remaining inaccessible portion of the cargo from its unapproa'chable loca-* tion to points below hatchways, by means of a self-propelled shoveling, lifting, carrying andunloading apparatus Another object of my invention is the provision of a self-propelled apparatus capable of being lowered through a hatchway of a boat and of being propelled about on the cargo supporting floor of the hull of the boat, said apparatus having means for shoveling cargo, retaining cargo on' the shovel, and after the apparatus is moved to the point.

pointdesired, depositingthe cargo at that With these and other objects in view, my'

invention consists in a self-propelled vehicle provided with shoveling ---and dumping mechanism and with. means for operating the vehicle and the said shoveling and dumping mechanism, and it also consists in thearrangement, and combination of devices and in the construction, arrangement, and combination of parts to be hereinafter described and particularly pointed out in th'esubjoined claims.

Referring now' tothe'drawings in detail, like letters of reference refer to like parts in'the several figures.

The reference letter A represents a vehicle, in preferred form comprisinga frame a mounted on wheels a a; the wheels at being the driving-wheels which are located at the front end of the frame and the wheels a being the steering-wheels located at the rear end of the frame. These wheels may be of'any suitable construction and are preferably arranged close together to provide a short wheel-base so that the apparatus can be easily turned about in the hull of a boat. Located at the rear end of the frame is the power-mechanism, in' the form of an engine Arum. orrrcn.

or motor B, which provides the power for 1 operating the apparatus. Suitable transmission mechanism 6 is inter osed between the driving-wheels a and sai ower-mechanisnLx A seat C may be provided [or the operator and a guiding-wheel 0 arranged in such relation to the seat that the operator occupyin the latter can convenientl steer the vehic e about, said guiding-wheel aving connection with the steering wheels a by means of a rod 0 or otherwlse.

The arts thus far described, constitute a 'powerriven or self-propelled vehicle, and

rising from the frontend of the frame A, are two supports D which are bolted or otherwise secured at their lower ends to said frame and are provided at their upper ends with alined openings (1 through which a rod E is passed, said rod extending with opposite ends a suitable distance through said openings and having its extremities reduced in diameter, as at e, and threaded for a purpose to presently appear.

'Suspended from the rod E is a shovel supporting-frame F comprising two side members f, f, each formed of sheet metal and having an opening f near its upper end into which is fitted the boss of a casting G.

These castings are riveted to the side members in a secure manner and through them are passed the reduced extremities e of the rod E, which provide a secure support for the shovel supporting-frame. The side members of the said frame are held on the reduced extremities of said rod by means of "from the extremities of the rod E, it is permitted to oscillate; but to limit the extent of oscillation, the side members of the shovel "supporting-frame are provided with alined slots I throu h which are passed bolts z thatare held in t e wheeled frame a, the shovel supporting-frame being limited'in its movements by the ends of said slots striking the bolts J represents a shovel which is normally supportedby the shovel supporting-frame F and is adapted for movement verticall thereon. This shovel comprises a rear wal 7', an inclined bottom or shoveling wall j widened at its front end, as at 9' and sides j flared at their-front ends, as at 3", to conform to. the widened front end of the bottom or shoveling wall 3'. Secured to the back j of said shovel, are two transverse bars 3',

one arranged at the upper end of the back and the other at the lower end thereof, and between these bars are arranged a pair of vertical stiffening bars j, preferably I- beams. The transverse bars 3" have cylindrical ends on which are mounted for rotation guide-wheels 9' arranged 1n pairs at each side and which'travel in guide-slots K formed in the side members of the shovel supporting-frame. At the front end of the bottom or shoveling wall j I secure a wearplate j the same being riveted to the underside of said wall and having a raised intermediate portion j which serves to guide the shovel for movement over the floor during, its shoveling action. Each guide-slotK has a vertical or substantially vertical lower straight portion hand a curved upper portion Is and the edges of these slots are faced I with T-shaped bars L riveted or otherwise suitably secured to the, side-members to form tracks, the lower ends of said bars extending onto'the removable lower sections f of the side members to which they are riveted, thus aiding to securely hold said sections to the upper portions of said side 1 members. The T-shaped bars provide extended track surfaces for. the guide-wheels j and are capable of withstanding considerable strain. The rear wall of each slot is provided with a notch at its lower end, as at M, and the front'wall of each slot has a similar notch M in a higher plane; and when the shovel J is in normal position, the lower pair of guide wheels thereonengage the notches Mwhile the upper pair of guide wheels engage the notches M thus offering resistance to the raising of the shovel. The purpose-of these notches is to prevent the shovel rising in its guide-slots during the act of shoveling material, as the resistance placed against the front end of the shovel has a tendency to raise the rear of the same. The shovel is elevated by means of cables N secured thereto and passing up and over the cable sheaves H, thence down and around drums O, 0 carried by the wheeled frame. These drums are operatively connected with the power mechanism B and by means of suitable clutches P, P may be thrown out of operative connection, said clutches being actuated in any suitable manner by means of a lever Q, arranged within convenient reach of the operator. As. there is considerable resistance placed against the shovel when the vehicle is propelled forward against the material to be shoveled, the shovel supporting-frame is caused to swing on the rod E, and although the extent of its movement is limited by the slots I in the side membersthereof, I deem it desirable to provide means for yieldingly taking up the jar which the apparatus would be subjected to by comin suddenly in contact with the material to e shoveled; and for this purpose spri'ng-receiving pockets R in the form of castings are secured to the side members of the shovel supportingframe and similar pockets S to the wheeled frame and in these pockets I place the ends of buifer-springs T. At a point between the ends of theguideslots K, I provide yokes U, one endof each being secured to the side member in front of the slot and the other end in rear of the slot, thus preventing buckling of the side members and the forcing of the walls of the slots together under the strain to which the apparatus is subjected while in theaction of shoveling.

When the shovel is in its normal position shown in Fig. -1, the front edge thereof isin contact or almost in contact with the floor, and with the shovel in this posit-ion, the vehicle is propelled forward to take up a shovel full of the material. The operator then stops the vehicle allowing the engine to run idle, he next throws in the clutches P, P, to cause rotation of the drums O, whereupon the shovel is raised in the shovel supporting-frame and when it reaches the position shown in Fig. 5, the clutches P, P are thrown out and the drums held against movement in any suitable manner. When the shovel is in the position shown in Fig. 5, the material is .held thereon by reason of the shovel having been tilted backward slightly. The.

operator then places the driving. wheels of the vehicle in action and causes the vehicle to be propelled to the point where he desires .to dump the material. Whenthis point is reached, he stops the'vehicle and again throws. the clutches P, P into ooaction, causing the drums O, O to rotate, thus elevating the shovel from the position shown in Fig 5 to that shown in dotted lines in Fig. 1. By reason of the guidewheels j of the shovel following the upper curved portion of. the track, the shovel "is caused to tilt forwardly, thus bottom of the shovel a greater mclination and compelling the material carried thereon to be dumped.

It will be noted that when the shovel is in normal position the bottom is inclined forwardly and the rear wall also inclines forwardly a trifle. Upon elevating the shovel a distance, after having a load of material, the u per guide wheelstravel upwardly and s ightly rearward until they reach, the rearmost points of the guideslots, thus tilting the shovel to recline the back thereof rearwardly and to bring the bottom thereof into a position more closely approaching the horizontal; and when in thls position, the material is retained on the shovel. Now upon drawing the shovel upward to its highest position, the upper guide-wheels 3' thereof travel-forward and the lower guide wheels travel rearward thus tilting the shovel to a position where the material can no longer be retained thereon. This advantage is obtained by the relative position of the guide-wheels on the shovel and the formation of the guide-slots. It is apparent, however, that other means for accomplishing the same purpose may be regiving the self to details of construction or formation of parts as I desire the subjoined claims to be given the broadest interpretation permissible by the prior art.
